TSB Report - April 2007 Trail, B.C.
Gatineau Quebec - The Transportation Safety Board
of Canada (TSB) today released its final investigation report into the 23 Apr 2007 train derailment in Trail, British
Columbia.
The Board is satisfied that improvements made as a result of its investigation will help ensure that trains can safely descend steep
mountain grades.
During the course of the investigation, Transport Canada issued a Notice and Order requiring that crews operating trains on the 4.1
percent grade between Warfield and Trail ensure that brake pressure retainers are functioning properly and set correctly.
The Canadian Pacific Railway (CPR) has since amended its procedures to comply.
Additionally, Transport Canada agreed with a TSB Rail Safety Advisory regarding the absence of the dynamic brake holding feature on
both locomotives involved in this derailment.
As such, Transport Canada is proposing a regulatory amendment to require that locomotives with a dynamic brake holding feature be
operated on territories with a grade of 2 percent or greater.
On 23 Apr 2007, a train with two locomotives, eight loaded hopper cars, and three residue tank cars ran uncontrolled down
the 4.1 percent grade between Warfield and Trail.
This led to the derailment of the two locomotives and the eight hopper cars.
A foreman and helper had detrained before the derailment and sustained minor injuries.
The locomotive engineer remained on board and sustained fatal injuries.
The TSB is an independent agency that investigates marine, pipeline, railway, and aviation transportation occurrences. Its sole aim is
the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal
liability.
